Hi! Today I'm gonna show you my latest thing I've done in Eagle. It's not something hard or very impresive, but it's useful and it can help you to spare some wires and you can avoid the breadboard for small projects.
As you can see I'm not a pro in using CADSoft Eagle, but if you're not happy with my layout you can modify the schematic anytime you want!
If you watch closely the schematic I added pins for 4 i2c devices with the corresponding 4.7K resistors, a voltage selector between 3.3V or 5V and D0 and D1 pins are compatible with serial bluetooth modules like HC-06 I have laying around.
For future improvements I want to add a separate voltage regulator or at least a port to connect a switching power supply.
You can find the schematics RIGHT HERE!
Greetings and happy new year! :)
